Qther objects will in part be Obvious, and

Be it known that I, FRANK B. HOWELL, a vin' art be hereinafter pointed out.

o the attainment of the aforesaid objects and ends myrinvention consists inthe novel.` details of construction,v and in... the combination, connection and arrangementof citizen of the United States, residing at Buffalo, Erie County, in the State of New York, have in'vented certain new and useful Improvements-in Boiler Jackets, of which the following is afull, clear, and exact specification. l 4

My invention relates to improvements in boilers, and the same has for itsobject more particularly to provide a'simple, efficient and reliable jacket for boilers and analeous structures which may be readily sei cured to or removedv therefrom.

Further, said invention has for its 'object to provideI a ljacket formed of a vpluralit of parts or sections which may be readily assembled and secured togetherin position upon a boiler.

Further, said invention liasfor its object to provide'a jacket formed of a' plurality of parts or' sections cachot` which is provided upon itsinner side with asuitable-v lining member or layer of heat-insulating' material, and said jacket parts or sections so constructed and arranged that the-sameA maybe secured together-.to form a complete enclosure'for a boiler. t Further, said vinvention has for its object to provide a jacketl formedl of a pluralityv .ofi parts or sections each of' which is vprovided with a layer or lining of heat-insulat--' ing material secured thereto whereby to per-l mitof said jacket `.sections being conveniently adjusted in .position upon a' boiler,

andl then secured along their contiguousedges in order to hold 'said sections duly assembled and in position upon a boiler.

Further, said invention has for its object te provide a jacket composedv of a plurality of parts or sections and a liningfof heatinsulating materialsecurcd vto Vand supported upon each of said parts or sections in suoli manner that the saine. cannot heuoine displaced or injured either in the process of applying the same to 'tl'1'e'boiler,or as aresult of the use of thc boiler thereafter. j

Further7 said invention has for its object to prov/ide a novel and convenient n'ieans f vsecuring the several parts or' sections OI the jacket together and in place upon a boiler.

parts hereinafter more fullydescribed and then pointed out in the claims.

In the accompanying drawings wherein like numerals of reference 'indicate like igure 1 is` a front elevation of a boiler equipped with one form of jacket or covering constructed according to, and embodying my said invention;

and in section on the partly broken away line 4- 4 of Fig. 2;-

F-ig. 5 is an enlarged detail vertical 'in lposition thereon oping the same.

and completely envel- The l'jacket 11 is preferably made of sheet' metal and. comprises a. front l2, a rear or back; a top 1.4, and

side members 15. Tin,l

rear :sectionvis of the same form substanse'ction 12. 'lhe front able openings corresponding with the fuel openingy `sl1c1ngopen1ng, ash-pit opening and fine openings ofthe boiler.

'fuel openings is secured a frame 16, provided with a door v17",'and over the remaining openings is secured a single large plate 1S provided with a slicing door 19, ash-'pit ,door 20,. and flue do The jacket sectio ors 20,

n at thc rear of lthe boiler is provided With the usual opening 11 registering with the outlet of the smoke Yilue of the boilcrover which is secured a frame having a col lar-'or other suitable member l1b for connection with a smoke he jacket ll the sidel Over the iev I,ber 1l intermediate said corners bent downwardly at right angles thereto to4 form flanges 1&1a which overlap the upper edges of the front, back and side members of said jacket. i

ln order to give additional strength and rigidity to the jacket members, `and to permit'ol the due securement of the adjoining parte to each other as Well as to produce a finished appearance the four vertical -and the four horizontal edges of the jacket are bound with angular edge members consisting of angle iron strips 21, 22, respec-A tively. The horizontal angle members or strips 21 have the ends of their laterallyextending portions mitred, as shown at Fig. 3. The opposite longitudinal edges of said angle members or strips 21, 22 are folded or doubled to form rounded edgesl V21, 22E, respectively. The upper ends of the vertical angle members 22 are squared and terminate immediately below the lower edges 21 of the horizontal angle members 21, as shown at Fig. 2.`

In order to reinforce the four'upper corners of the jacket, and at thesame time to give the same a finished appearance heavy corner pieces or members 23 formed of cast iron or of other suitable material are dis-- lace by posed "thereon, and secured in bolts 2li comprising threaded en sA 25, 26 arranged at right angles to each other and connected by a diagonal portiony 27.

En order to form a perfectly secure and rigid joint at the four upper corners of the jacket the side wall members 15, the flange 15, the front member 12, the vertical portions of the top flanges 14, and the rertical side portions'of the corner members are provided with horizontally .elongated apertures 25s` through which the threaded ends of the bolts 24 are passed and then secured by cap nuts 29.

The remaining portions -of the vertical edges of the jacket, as Well as the portions of the horizontal edges of the jacket are secured together by bolt. which correspend in 'shape' to the bo ts 2st. The bolts 30 vdo not extend through the corner mem bers 23, but only through suitable apertures provided in the two portions of the vertical angle members 22, the side members 15, the flange 15B thereof and the front jacket member 12.

The lower horizontal edges ot' the side members l5, and of the backmember of the jacket are turned inwardly at right angles thereto in order to forni supporting tlaxigcs 3l lupon which rest the lower edge of the insulating lining sections 32. The said lining sections 32 are riveted or otherwise fastened at suitable intervals to the side Walls l5 in order to prevent the buckling or displacement thereof. rThe saine manner of securement is employed in connection with the lining section for the' top 14.

It will be noted that by means of my invention a boiler ma be completel enclosed and insulated by a jacket ot sectional constructionfwhose parts are so constructed and arranged with respect to the other parts thereof that the same produces the appearance of a single or unitar structure, and that theangular bars disposed upon the vertical and horizontal edges` which cooperate withthe bolts and nuts to hold the parts rigidl secured together,

.also serve to conceal t e joints formed at the meeting edges of the. several jacket parts, and thereby produce a neat and iinished appearance.

It is to be noted also that boilers used for domestic and other heating` purposes are usually installed in cellars or laces having low ceilings, and as such oilers are usually of considerable height the jacketing thereof is very frequentl r rendered extremely ditiicult owing to tli small amount of head room. This diliculty has been overcome by means of my inventionhereinabove set forth in which the sectional construction of the jacket with each element separately linedrenders it extremely easy tp apply the same to a boiler.l Further, the securement of the jacket in place upon the boiler is a lso rendered extremely simple and convenient by reason of the novel securing 'means employed.
